Preparation method of hippophae rhamnoides fruit Fuzhuan tea

The invention provides a preparation method of hippophae rhamnoides fruit Fuzhuan tea. According to the preparation method disclosed by the invention, hippophae rhamnoides leaves are subjected to an enzymolysis reaction in advance through compound enzymes (cellulase, hemicellulase and pectinase), so that enzymolysis effects better than those through the hemicellulase singly are obtained, the compact structure of cell walls of the hippophae rhamnoides leaves is well destroyed, flavone with different molecular weight in the leaves can effectively penetrate through the cell walls to dissolve in tea soup, the flavone leaching rate is effectively increased, and the utilization rate of total flavone in the hippophae rhamnoides fruit Fuzhuan tea is increased. 本发明提供了种沙棘茯茶的制备方法。本方法利用复合酶（纤维素酶+半纤维素酶+果胶酶）对沙棘叶片预先进行酶解反应，得到了比单用半纤维素酶效果更好的酶解作用，较好的破坏了沙棘叶片细胞壁的紧密结构，促使叶片中不同分子量的黄酮能够有效穿过细胞壁溶解于茶水中，有效增加了黄酮浸出率，增加了沙棘茯茶总黄酮的利用率。
